These forests are biodiversity hotspots, supporting a vast array of plant and animal species. The complex structure of the forest, with its multiple layers of vegetation, provides habitats for a wide range of organisms, from towering trees to tiny insects. Many of these species are endemic, meaning they are found nowhere else on Earth. Protecting temperate rainforests is essential for preserving this unique biodiversity.

Climate Regulation (Regulação Climática)

Temperate rainforests play a crucial role in regulating the global climate. The dense vegetation absorbs large amounts of carbon dioxide from the atmosphere, helping to mitigate the effects of climate change. Additionally, the forests release water vapor into the atmosphere through transpiration, contributing to regional rainfall patterns and moderating temperatures. Their capacity to store carbon makes them invaluable allies in the fight against global warming.

Water and Soil Conservation (Conservação da Água e do Solo)

The dense vegetation and extensive root systems of temperate rainforests help to protect water and soil resources. The forests act as natural sponges, absorbing rainfall and releasing it slowly into streams and rivers, preventing soil erosion and reducing the risk of flooding. The water that flows from these forests is often of high quality, providing a valuable source of drinking water for nearby communities. Healthy temperate rainforests are essential for maintaining clean and reliable water supplies.
